Be-it known that I, FRANK FESSLER, a citizen ofthe Un1tedStates,2-,ndresident of Des ble of adjustment for. varying the positions betweenrows of such chairs.

,The obj ect'of my invention is to, provide an opera chair soconstructediand supported 7 that the chair sea-t maybe swung rearwardly,

so that-,thetotal space from front to rear occupied by the chairwill-not bematerially :increased, and yet: the ,distancel between; the

chair beingioperatedanda the rowiof chairs in front may be variedfor-leaving: agreater orless space through which patrons of the 20 a somounted that theseat and back maybe ,swungor tilted. from position wherethe back is inclined upwardlyand rearwardly to posi- 251 tion where theback issubstantially vertical, the lower partjof the baokrbeing swungrearwardly for therebvallowing a greaterspace in front of the chair. a v

,lVith these [and other objects in :view, my invention relates qto-gtheconstruction, =;ar-

rangement and combination of the various parts of the device, wherebythe objects conopera chair embodying my invention,.rthe,

dotted lines showing the chair in its rearward position.

Fig. 2 shows a front elevation of said chair, and

Fig. 3 shows a vertical, sectional view taken on the line 33 of Fig. 2.

In the accompanying drawings, I have shown an illustration of one formof my opera chair, having the seat, which is indicated by the referencecharacter 10, the arms 11 and the back 12.

I provide beneath the forward portion of the seat a bracket 13 havingforked, spaced, upwardly extending arms 14, pivotally secured to thebottom of the seat near opposite sides thereof, and near the forwardportion thereof, as illustrated in Figs. 1 and 2. At

Specification of Letters Patent. Patgnted N 20, 19121 -Applicationfiled--March 13,1917. nSeriaLNo. 154,621.

, its lower end the bracket 13 is provided With I spaced, forked, arms.1!, which are pivoted to the floor upon which, the chair is supported.

Rearwardly of thebracket is a bracket 16 having-arms 14, similar tothose already described, pivoted to the bottom of the seat rearwardlyof" the pivot points of the first arms 14 and near the side edges-of theseat.

The bracket 16 is provided at its lower end -with arms 15, similartothose already ,de-

scribed, and similarly pivoted to the-floor.

It should be mentioned 111 this connection that the distance between theupper ends of the brackets-13 and 16 is substantially less than; thedistance betwcenthc lower ends thereof, and that the total -length ofthe bracket-16 from the chair seat to the floor is 117 closed at itsends. I

Rotatably but non-slidably mounted on T the bracket 16 is a bolt18,:extending forwardly andcslightlyl downwardly. The forward portion ofthe bolt 18 is screw-threadecl-at 19. On the'forwardend of the bolt lSis screwed an elongated socket 20, theforward end of which travels 1nthe channel 17. 1111; the practical construction and opera- 1 tion of myimprovedopera chair, itmay; be noted that the; back 12 may be'arrangedat any desired angle with relation to the seat 10. I have shown onearrangement of the parts, in the drawings.

Inthe normal position-of, the chair, as Shown in the drawings, thebrackets 13 and 16 extend upwardly and forwardly from the floor, and theback 12 is inclined from its lower end upwardly and rearwardly withrelation to the floor.

The engagement of the forward end of the socket 20 with the lower end ofthe channel 17 prevents the chair seat from swinging downwardly andforwardly beyond a certain predetermined position.

If a person is seated in the chair and someone attempts to pass in frontof the person so seated, the person seated may push the seat of hischair rearwardly to the position shown in dotted lines in Fig. 1. Itwill be noted that the seat and the lower portion of the back will swingrearwardly a considerable distance, but that the upper 1 Copies pr thispatent ma be obtained for engages the upper end of said channel,

whereby the rearward and downward movement of the seat '10 is limited. 1r

It will be seen that by adjusting the lower ends of the brackets13 and16 rearwardly Y or forwardly on the floor 1, considerable variation inthepositions and adjustment of the chair may be secured, and the socket20 is adjustably mounted on the bolt 18- for accommodating and makingpossible such adjustment andfor causing the bolt 18 and socket 20 toserve as a limiting device in all positions of said adjustment. Theentire-device is of very simple and inexpensive construction and permitsthe rearward and forward swinging movement of the'seat with very littleinconvenience'ito the persons behind the seat beingmoved;

On account of the rearward position of the back 12 in the-forwardposition of the seat, it will be seen that the seat 10 may be movedrearwardly a considerable distance forallowing a space in front of theseat, and for reducing the total space from front to rear occupied bythe seat by'swinging the back 12 from its rearward position to itssubstantially vertical position.

Itwill, of course, be obviousthat the dis- "tance .of-the'swing-may bevaried as may be desired.

I claim as my invention:

An opera chair having a seat and a "back, a bracket pivoted to saidopera chair seat near theforward end thereof, and designed to be pivotedto the floor, asecond bracket'InVOtedIto said opera seat rearavardly ofthe upper point of attachment of the, forward bracket, and designed tobe pivoted to the" floor, said brackets'being of different lengths fromtheseat to their lower ends, a member secured to one of said bracketsand extending toward the other, and means on said other member forlimiting the up and down movement of saidmemher, said means comprising achannel having closed upper and lower ends.
